Abstract:
The present invention provides a spheric catalyst component as well as a catalyst for olefin polymerization. The spheric catalyst component comprises at least one titanium compound and optionally at least one electron donor compound supported on an active magnesium halide spheric carrier, wherein the active magnesium halide spheric carrier is solid particles obtained by dispersing a melt of magnesium halide/alcohol adduct by rotation under high-gravity field. The catalyst has good particle morphology and narrow particle size distribution, and when used in olefin polymerization, especially in propylene polymerization, exhibits relatively high activity and stereoelectivity, and gives polymers having good particle morphology and high bulk density.
Abstract:
A method of processing a substrate, where the substrate is transferred from an ambient environment into a clean environment. The substrate is heated to at least a first temperature within the clean environment, and then maintained at no less than the first temperature within the clean environment. The substrate is selectively transferred within the clean environment to more than one processing chambers, and processed in the more than one processing chambers. The substrate is transferred from the clean environment into the ambient environment.
Abstract:
An improved polarization beam splitter formed by a collimator and two similarly shaped, birefringent crystal prisms is provided. The light from the collimator is incident upon the first face of the first birefringent crystal prism which also has second and third faces. The collimated light is incident upon the second face at an angle .phi. with respect to a line normal to the second face so that light polarized perpendicular to a plane of incidence upon the second face is reflected toward the third face and light polarized in the plane of incidence is refracted at the second face. The second birefringent crystal prism has a second face parallel to, and in close proximity with, the second face of the first birefringent prism so that light refracted at the second face of said first prism is refracted at the second face of the second prism and into the second prism. A first face of the second prism is positioned with respect to its second face so that light refracted into the second prism is refracted at the first face from the second prism cross-sectionally undistorted with respect to a cross-section of the light polarized in the plane of incidence at the second face of the first prism. This polarization beam splitter can handle high power without distorting the beam.
Abstract:
A method and apparatus for adaptive de-blocking filter are disclosed. One or more parameters associated with a de-blocking filter are determined. De-blocking filter using the derived parameters are then applied to reconstructed blocks. Each set of parameters is used for each picture, slice, coding tree unit (CTU) or CU (coding unit). The parameters can be signalled in VPS (video parameter set), SPS (sequence parameter set), PPS (picture parameter set), slice header, CTU (coding tree unit) or CU (coding unit) of the video bitstream. The parameters correspond to one or more values used as thresholds, clipping boundaries, or both the thresholds and clipping boundaries for the de-blocking filter. In one embodiment, the parameters for the current picture are determined using a training process using a current coded picture a previous coded picture as training data.
Abstract:
Improvements in a bracket is disclosed for mounting an electrical box onto a mounting bar. An electrical box can be preinstalled onto the bracket and clamped onto the mounting bar using wings. Bendable tabs can be articulated to secure the bracket and onto a rail. Fasteners are used to secure an electrical junction box onto the bracket and an additional fastener secures the sub assembly to the rail. The tabs can be unbent for removal. An installer can secure the bracket and electrical box using a screw and adjust the position of the bracket on the mounting bar. The bracket provides a low profile assemble that allows the bracket to be installed between the inner surfaces of stud walls.
Abstract:
According to the invention, generally, a microfluidic aliquoting (MA) chip, adapted to fit in a Petri dish, has a center well (inlet) connected by branched channels to a plurality of side wells (outlets). The chip comes in various types, including a bMA Chip T1, bMA Chip T2, bMA Chip T3, and an rMA Chip. The branched channel improvement provides for a greater distance between neighboring channels and a decreased density near the center well. Design improvements including an injection mold design for an insert and a base and a multiplex hole punch allow for rapid fabrication of the MA chip.
Abstract:
Improvements in a conduit locking connector that connects rigid conduit to an electrical junction box. Rigid conduit provides the benefit of allowing an installer to screw onto the side of the rigid conduit to frictionally lock into the rigid conduit with the conduit locking connector. A screw engages into rigid conduit that provide a hard bearing surface on opposing sides of the screw. This provides minimal bending of the rigid conduit for a firmer grip of the rigid conduit to the conduit locking connector. The conduit locking connector provides a physical interface that locks onto the rigid conduit and locks onto the junction box. The conduit locking connector provides anti-rotation between the rigid conduit and the junction box. Anti-rotation is with tabs that extend below a planar surface of the conduit locking connector and engage into holes in recesses in the junction box.
Abstract:
A method and a device for processing geological information is disclosed. The method for processing the geological information includes acquiring multiple geological image graphs, determining the relation between the image coordinate and the ground coordinate of each of the multiple geological image graphs by an imaging mode of geological images, and joining the multiple geological image graphs together according to the relation between the image coordinate and the ground coordinate of each of the multiple geological image graphs. Accordingly, large-scale ground images can be acquired by processing the geological images.
